A video appearing to show Bradley Cooper and girlfriend Irina Shayk in the middle of a lovers' tiff at the Wimbledon final has emerged online.

The Hangover star and the Russian supermodel were among celebrity guests watching Scottish tennis star Andy Murray win the men's singles final against Canada's Milos Raonic at the tournament in London, England, on Sunday. During live coverage of the match, the camera cuts away from play to the audience and catches what seems to be awkward moment between the couple, who have been dating since April, 2015.

The footage, which has been uploaded to Twitter, shows Bradley twisting in his seat to face Irina and chat, but she looks away from him and repeatedly wipes at the corner of her eye, leading many social media users to speculate if she was crying. After she continues refusing to look at him, Bradley sit back in his chair and watches the game.

Other pictures taken of the audience show Bradley whispering in Irina's ear while she is preoccupied with her cell phone, and both watching the sport in apparently stony silence.

It isn't known what caused the tension between the couple, but a number of fans have noted Bradley's ex-girlfriend Suki Waterhouse was also seated in the crowd. She dated the actor for two years until early 2015.

They weren't the only celebrities in the audience - Bradley and Irina were sat next to Benedict Cumberbatch and his wife Sophie Hunter, while Hugh Grant, Ellen DeGeneres and British royals the Duke and Duchess of Cambridge were also in attendance.

Bradley and Irina's awkward moment is a stark contrast to their previous visit to the tournament earlier in July (16), when pictures showed them smiling, giggling, and snuggling into each other.
